Rose plant Jacaret

ABSTRACT

A floribunda rose variety having vigorous, productive plant growth, small and double red flowers having a definite fragrance, few thorns and resistance to mildew.

This present invention relates to a new and distinct variety of roseplant of the floribunda class which has originated by me by crossing anunnamed variety with the variety Caper, U.S. Plant Pat. No. 3,937.

The primary objective of this breeding was to produce a new rose varietycombining the colors of both parents in a variety suitable for abundantproduction of small flowers usable as cut flowers. This objective wassubstantially achieved along with other desirable improvements asevidenced by the following unique combination of characteristics whichare outstanding in the new variety and which distinguish it from itsparents, as well as from all other varieties of which I am aware:

1. A vigorous, productive plant, freely branching to produce small redbuds.

2. Open flowers are small, double (40 petals), red.

3. Definite fragrance.

4. Few thorns.

5. Resistance to mildew.

Asexual reproduction of this new variety by budding, as performed atWasco, Calif., shows that the foregoing characteristics and distinctionscome true to form and are established and transmitted through succeedingpropagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor in terminology in accordance with The Royal Horticultural SocietyColour Chart except where ordinary dictionary significance of color isindicated.
